Abstract

The parent patent described electrode material of the type LaNi5 in which the La and/or Ni are partially substituted by a metal selected from gps. Ia, II, III, IV and Va not including the lanthanides, in an atomic proportion of 0.1-25(0.5-15)% with the La. The electrodes so produced exhibited an entranced power of storage and retention of H2 in an electrochemical medium tottemps. considerably above ambient. Hence the batteries can be worked in quasi reversible manner. In this addition, patents, the La and/or the Ni are partially substd. by a gp. IIIb metal in an amount of 0.1-30 (0.5-15)% w.r.t. the Ni. Improved properties can be obtd.; the retention of the H2 being possible at up to 60 degrees C. H2 absorbed can be held in reserve for long periods.
